Balance device of internal combustion engine

Abstract

The invention discloses a balance device of an internal combustion engine, which relates to balance technology of a reciprocating piston internal combustion engine. The ride comfort of an existing internal combustion engine, particularly a line four-cylinder internal combustion engine, is much poorer than that of a V-type internal combustion engine due to the fact that a quadratic term portion of vibration of movement of a piston of the existing internal combustion engine cannot be balanced. The balance device is characterized in that a counterweight with a certain mass is driven by a reciprocating control device to reciprocate, accordingly, more complicated vibration can be balanced, each cylinder of the internal combustion engine can be independently and dynamically balanced, fuel economy is improved, and Atkinson cycle internal combustion engine which cannot realize dynamic balance easily can be widely applied. The balance device can also be used for balancing more other types of vibration including vibration with varying vibration strength, varying vibration amplitude and varying vibration frequency, damping vibration and self-excited vibration, and can also be widely applied to vibration elimination in the mechanical field.

Description

technical field [0001] The invention relates to a balancing device of an internal combustion engine, which is a balancing technology of a reciprocating piston internal combustion engine. The invention can fully balance the quadratic forced vibration of the internal combustion engine and any other vibrations, including vibrations with variable vibration intensity, amplitude and frequency. The self-balancing of a single cylinder of the internal combustion engine can be achieved by using the invention, so that the internal combustion engine with fewer cylinders can be widely used, and thus the fuel consumption of the internal combustion engine can be reduced. Background technique [0002] Generally, an internal combustion engine, whether it is an inline four-cylinder or six-cylinder, and a V-shaped cylinder arrangement, will inevitably have some vibrations. The high-efficiency Atkinson cycle machine cannot be applied on a large scale. The main obstacle is not the low efficienc...
